CHURNL SPECIFICATION forming part of Letters Patent N o. 266,219, dated October 17, 1882.

Application filed May 13, 1882. (No model.)

To all whom fit may concern Be it 'known that I, FRANK P. STEBB1Ns,a citizen of the United States, and a resident of Detroit, in the county of Wayne and State of Michigan, have invented a new and valuable Improvement in Ghurns; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings, making a part of this speciication, and to the letters and figures ot' reference marked thereon.

Figure l of the drawings is a representation of a vertical sectional view of my churn and freezer. Fig. 2 is aside view of the same, and Figs. 3, 4, 5, and 6 are detail views.

This invention has relation to chnrns and cream-freezers; and it consistsin the construction and novel arrangement of the studded catches for the lid-sections, the separable arm or support for the drive-wheel, and its double bearing for the upper ends of the dasher-stems, the plate-sections for the'lidsections, and the socketand-tongue counectionwith which they are provided, all as hereinafter set forth.

In the accompanying drawings, the letter A designates the case, which is of ordinary upright form, having a circular area in horizontal section.

B B indicate the cover-sections, each being semicircular and marginally rabbeted at a to form a lip, b, which fits within the mouth ot' the case, and a marginal rim-flange, c, which projects outward over the edge of the case.

G (l represent the dashers, which are made in loop form, being cast of metal. Thelower end ot' each loop-dasher is formed with asupporting-stem, d, which works in a pivot-bearing, c, at the bottom of the case. The upper end of each loop-dasher is formed with a vertical stem, g, which extends upward through a bearing at thejoint of thecover-sections, and is provided with a pinion, h, as' indicated in the drawings. The pinion is secured on the stem by means of a spline, k, which is cast on the stem, so that, while it is fast thereto for all purposes ot' communicating rotary motion, it can be easily and quicklj1 removed. Each stem is cast with ashoulder, l, below the spline, on which the pinion rests. The side bars, m, of each loop-dasher are cast with oblique longitudinal ianges f on their outer edges, these anges being turned in opposite directions von the side bars, so that the V-form channelsf, which lie between the flanges and the side bars, will face or open in opposite directions, as shown. The object of these channels is to aerate the milk or cream as the loops are turned. The stems of these dashers are placed sufciently close together to allow each loop, in its rotary movement, to intersect the path of the other without interference.

D D represent the semicircular plate-sections, which are respectively secured to the upper surfaces of the cover-sections at their middle and adjacent portions, so as to form, when closed together, an iron bearing which is concentric with the periphery of the cover. The plate Dl is formed with a lug at its edge, carrying a projection, p, which extends across thejoint of the meeting edges of the two sections, and is enlarged at its outer end, as indicated at p', forming a coupling-tongue to engage a slotted socket-recess, 1^,ot` corresponding form, which is madein a large lug, l', cast on the top of the other plate-section, D. The lug l' is also formed with a square socket, s, extending downward into its upper portion, which is designed to receive the squared tang t of the double bearing-arm E. A pin, e, passing through registering-perforations in the socket s and tang t, serves to secure the arm in its seat in such a manner that, while it is perfectly secure, it can be easily removed. This arm E is formed with two lateral bearings, az, in which the upper ends or journals of the stems g of the dashers are seated, and with an upward and lateral extension, F, carrying a transverse bearing, w, for the driving gearwheel G, which engages a bevel-pinion, H, on the stem g, over which the laterally-placed bearing wis situated, as indicated in the drawings.

K represents a transverse handle on the eX- tension F, in rear of the bearing w, which is designed to enable the operator to steady the machine with one hand while turningthehandie of the drive-Wheel with the other. This construction is designed to form a strong and compact support for the gearing and dasherstems, whereby the drivingmechanism is maintained in proper position when the cover-sec- IOO tions are in place and duly connected by the tongue and socket of their iron plates, and the arm F is fastened in its seat, and it permits the ready removal of the driving meehanism when the case is to be opened. In this operation the pin fu is drawn out of the socket s, and the arm E, with the drive-wheel, islifted from said socket. The pinions can then be removed from the dasher-stems, if necessary.

In order to secure the cover firmly to the case-wall, the latter is provided with the edgeliooks L, which are fastened by studs `or rivets to said Wall, and, projecting by their heads above the same, serve to engage the rim-flanges c of the cover-sections, one of which is formed with an edge-nomina, to facilitate the engagement.

Having described this invention, what I claim, and desire to secure by Letters Patent, 1s-

1. The cover-plates D D', having a tongueand-socket connection, and a separable arm, E, for the drive-wheel, carrying a double bearl ing for the upper ends of the stems ofthe dashers, substantially as specified.

2. The cover-sections having the plate-sections D D', connected bytongnep and socket r, and the edgehooks L of the Wall engaging the rimflanges c of the cover-sections, substantially as specified.

3. The combination, with the dashers C, having the splined and shouldered stems g, and their pinions h H and the drive-Wheel G, of the coversections B, plate-sections D D', their socketand-ton gue connection, the socket s, pin c, and removable 4arm E, having the lateral bearings z, and the extension F, substantially as specified.

In testimony that I claim the above I have hereunto subscribed my name in the presence of two witnesses.
